To all whom it may concern.-

Beit known that I, MICHAEL S. GooLEY, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Rubbing or Polishing Machines; and I do hereby declare the following to'be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. c

My invent-ion relates to rubbingV or polish ing machines for polishing furniture, stone, or any article of manufacture; and the obj ect is to provide a machine of simple construc-4 tion wherein the several elements coperate to produce a device which is eflicient in operation and easy of manipulation.

The invention consists of a vertically-adjustable and horizontally-reciprooable carriage carrying the article to be polished, a polisher reciprocable at right angles to the` movement of the carriage, and means to start or stop the carriage-shifting mechanism synchronously withY the elevation or depression 4of the polisher.

The invention further consists in the construction, combination, and arrangement of parts, all as will be more fully described hereinafter and illustrated in the accompanying 1 drawings, forming a part of this application,

and finally pointed out Vin the appended claims.

In the drawings, Figure 1 is a side elevation l of the machine complete. Fig.'2 is an end elevation of the same. Fig. 3 is a view, partly in elevation and partly in section, of the standard, showing the manner of adjusting the `sleeve which carries the driving and transmitting pulleys. Fig. 4 isa side elevation of a portion of the machine, showing the polisher and the mechanismfor raising and lowering the same in their two positions, the dotted lines illustrating the position of the parts when the polisher is raised. Fig. 5 is a transverse section of the standard on the line .fr of Fig. 2.

Referring to the drawings in detail, in

which like characters of reference indicate.

corresponding parts throughout the several views, 1 1 designate the uprights on which the carriage, its adjusting mechanism, the

polisher, and-its raising and lowering mechanism are mounted, and 2 designates the standard on which the driving mechanism for the several parts is mounted. On the uprights are slidably mounted a pair of brackets 3, having a suitable track 4, on which the carriage is adapted to reciprocate, the carriage being provided with suitable rollers for the purpose. Extending parallel With the uprights 1 and mounted in suitable bearings at the top and bottom thereof are a pair of adjusting-rods 6, the screw-threaded portions of which are adapted to engage threaded apertures in the brackets 3 for the purpose of vertically adjusting the carriage on which the article to be polished is supported, the said rods being operated through the medium of a horizontal rod 7, journaled in the top of the uprights and having beveled gear connections with the rods 6, as shown.

The vertically-adj ustable carriage is adapted to be reciprocated horizontally on the tracks thy a mechanism 8, forwhich I have applied Kfor a patent in a cotemporaneous application, said application bearing Serial No.

For the purpose of clearness and to enable others to understand the operation of the polishing-ma chine this improved carriage-shifting mechanism, briefly, consists of lan oscillatory lever 8, pivoted at either end to a fixed support, and a rod 9, connecting the carriage and the lever. The shaft of the driving-pulley 10 is mounted in suitable uprights 11, which are vertically adjustable in the standards 12, and one end of the shaft of the pulley is connected with a suitable worm-gearing 13, having an arm 14 on the shaft of the worm-wheel, which is connected to the lever 8a by an arm 15.

On the standard 2 is slidably mounted a sleeve 16, in which the shaft 17 is journaled and on which are mounted the power-pulley, the transmitting-pulley, and the driving pulley for the polisher.

The pulley 19 is loosely mounted on the shaft 17 and serves to drive the pulley 10 of the carriage-shifting mechanism, through the medium of a belt 20, when the clutch 21, which is keyed to the shaft 17, is thrown into engagement therewith.

22 and 23 designate fast and slow pulleys,

either of which may be caused to rotate with the shaft by means of the clutch 24 and permitting the operator to use either' fast or slow.

speed, as desired. The clutch is operated by a push-bar 25, which connects with a lever 26, fulcrumed in a slot in the arm 27, which is supported at one end by an extension 23 of the sleeve 1G and at the other end by an upright 29 of a bracket 30. rlhe lever 3l for operating the clutch 2l is similarly fulcrurned in the arm 27 and is connected with a bellcrank lever 32 by means of a rod 33, the said bell-crank lever being pivoted to the extension 2S of the sleeve, as shown in Fig. 5. The other end ofthe bell-crank lever is in engagement with a rod 34, which connects with a crank-arm 35, journaled in the frame of the polisher and which operates with the mechanism for raising and lowering the polisher. This raising and loweringr mechanism for the polisher consists of a cross-head 3G, having a depending portion 37, in which the shaft of the crank-arm 35 is journaled. On this shaft are mounted a two-arm lever 38 and a handle 39, said lever being keyed thereto to adapt it to rotate therewith. The slotted beam 40, on which the head 40 of the polisher 40b reciprocates, is supported from the cross-head 36 by means of links 4l, which form toggle connections with a pair of arms 42, said arms being also connected to the arms of the lever 38, so that when the handle 39 is pushed to the position indicated by dotted lines in Fig. 4 the arms 42 and links 4l will be drawn inside and the beam 40 elevated, while a connecting-rod 34, which is secured to the crankarm 35, will at the same time be pushed and through the medium of the bell-crank lever, rod 33, lever 3l, and clutch 2l throw the driving-pulley 19 into or out of connection with the shaft, and thereby start or stop the carriage-shifting mechanism synchronously with the raising or lowering of the polisher. When the beam 40 is raised to the position indicated by dotted lines in Fig. 4, the counterweights 43, which are connected with the beam by means of a connection 44, will hold it in such elevated position.

The cross-head 36 and the beam 40 are vertically adjustable on the uprights l to adapt the polisher to be brought to any position ooincident with the position ofthe carriage;bu`t to insure the proper operativeness of the machine when so adjusted the sleeve 16, carrying the driving mechanism for the several parts, is vertically adjustable on the standard 2. This adjustment is accomplished by means of a windlass 45, journaled in a suitable bracket in the base of the standard and having a flexible connection 4G, which passes up over a pulley1 47 at the top of the standard, the other end being connected to the sleeve 16.y It will be seen that by turning the handwheel 48 the iiexible connection 4G will be wound on the windlass 45, and the sleeve, with the shaft which passes through a slot in the standard, together with the transmittingpulleys and driving-pulley, will be raised or lowered to correspond to the elevation of the polisher and its frame.

The article to be rubbed or polished is clamped between the jaws 49, which are movable relatively back and forth on a screwrod 50, and from the top of these jaws 49 extend shields 51, which catch the splash of oil or other materials used in polishing.

The operation may be stated, brieiiy, as follows: The article to be rubbed or polished is clamped between the jaws 49 on the carriage and the carriage adjusted vertically to the desired position. The handle 39 is then pushed until the arms 42 and links 4l assume the position shown in full lines in Fig. 4and the polisher depressed into engagement with the article. This operation, as previously explained, throws the clutch 2l into engagement with the gear 19 and through the medium of the belt 2O and the mechanism 8, which has previously been adjusted, as is more fully explained in the cotemporaneous application, shifts the carriage back and forth upon its guides or tracks 4. The clutch 24 is then thrown into engagement with one of the driving-pulleys 22 23 and the fly-wheel 52 is caused to rotate and through the medium of the pitman 53 reciprocates the polisher at right angles to the reciprocations of the carriage, thus bringing all parts of the article to be polished within range of the polisher.

Having thus described my invention, what I claim is- 1. In a polishing or rubbing machine, the uprights, a vertically-adjustable support for the article to be polished mounted on the uprights, a frame ou the uprights, a polisher carried bythe frame, said frame also carrying a means for throwing the polisher into and out of engagement with the article to be polished, and means for driving the polisher.

2. In a polishing or rubbing machine, a reciprocating polisher, means to raise and lower the polisher, a reciprocating carriage, means to operate the carriage, and mechanism to start or stop the carriage-operating means synchronously with the raising and lowering of the polisher.

3. In a polishing or rubbing machine, a reciprocating polisher, a carriage reciprocal at right angles to the movement ofthe polisher, means to reciprocate the carriage, means to raise and lower the polisher and means cooperating with the polisher' raising and lowering means to start or stop the carriage-reciprocating means.

4. In a polishing or rubbing machine, the combination with a vertically-adjustable, reciprocal carriage and means to operate said carriage, of a vertically-adjustable polisher reciprocal at right angles to the movement of the carriage, means to raise and lower the polisher to bring it into or out of operative position with the article carried by the carriage, said raising and lowering means cooperating with the carriage-operating means to start or stop the carriage synchronously with the engagement or disengagement of the polisher with the article.

5. Inv a polishing or rubbing machine, the combination with a vertically-adjustable, reciprocal carriage and means to operate said carriage, of a vertically-adjustable, reciprocal polisher adapted to move at right angles to the movement of the carriage, means to drive said polisher at different speeds, and means to vertically adj ust the driving means to bring it into operative position with the polisher.

6. A polishing or rubbing machine comprising uprights, a reciprocal carriage vertically adjustable thereon, a cross-head Vertically adjustable on'the uprights, a beam suspended from said cross-head, a polisher reciprocal on said beam, mechanism carried by the cross-head to raise and lower the beamx MICHAEL S.
